Resale values are important for those who upgrade often... What do you want to upgrade to if you have a polo?
You heard it's small, just check the dimensions, I don't think numbers lie, it's similar to jazz, unless you think jazz is small lar

err... why are you using wheelbase as comparison ar? what about width, height and length?
                                 myvi       Polo        jazz
Length (mm)         3,750     3,970     3,920
Width (mm)         1,665     1,682     1,695
Height (mm)         1,550     1,462     1,525
Wheelbase (mm) 2,440     2,470     2,500

fairer comparison above
